A method for manufacturing a fiber-reinforced hollow structural component includes introducing a mold core and fibers with a matrix material into a molding tool. A first fiber unit is located between the mold core and the molding tool to at least partially form a component wall. The matrix material is cured to form the hollow structural component and the mold core is flushed out of the hollow structural component to form a component cavity. At least one channel may extend through the mold core so that after the matrix material has cured and the mold core has been flushed out, a reinforcing strut is formed. A related hollow structural component is also disclosed.

Continuous compression molding process and apparatus for fabricating thermoplastic composite parts from pre-formed thermoplastic composite laminates with tooling dies have a staggered bevel feature at an entry side of the tooling dies. Staggering the length of the bevel feature in each section between bends in a surface contour along the width of the incoming edge of the tooling dies prevents excess material from being trapped and forming wrinkles in the finished thermoplastic part. The length of the taper in each section along the width of the tooling dies is aligned with a pulsed advancement distance of the pre-formed part.

Disclosed herein is a transverse tensioning system that comprises a left-side clamping assembly comprising a first left-side clamp element and a second left-side clamp element. The first left-side clamp element and the second left-side clamp element clamp down on the left edge portion of the stack of plies when the stack of plies moves in a feed direction and is shaped between opposing dies. The system also comprises a right-side clamping assembly, spaced apart from the left-side clamping assembly and comprising a first right-side clamp element and a second right-side clamp element. The first right-side clamp element and the second right-side clamp element clamp down on the right edge portion of the stack of plies when the stack of plies moves in the feed direction and is shaped between the opposing dies.

A transparent resin molded product and a mold for molding the product are provided in which occurrence of silver streak in the resin molded product is prevented. The resin molded product includes a design portion and a non-design portion, at least a part of the design portion is molded by transparent resin, and a gate trace (a gate arrangement position during the resin molding) is disposed in the non-design portion (runner portion). A foreign matter restraining portion for restraining foreign matters and bubbles contained in the transparent resin is disposed in the vicinity of the gate trace of the non-design portion. The foreign matters and bubbles are restrained by the foreign matter restraining portion and are prevented from flowing to the design portion, and therefore the occurrence of silver streak on the design portion can be prevented.

According to one embodiment, a mold includes a base, a first concave pattern, a second concave pattern, and a third concave pattern. The base includes a first surface and a pedestal projecting from the first surface. The pedestal includes a first region and a second region disposed outside the first region. The first concave pattern is formed in the first region. The second concave pattern is formed in the second region. The third concave pattern extends from the first region to the second region.

The present invention is a method and apparatus for molding plastic parts and placing and orienting reinforcing fibers within structurally thin sections. More specifically, the method of the present invention is a molding technique wherein positive displacement is applied to incremental sections of a charge (plastic mixed with reinforcing fibers), thereby sequentially forming the desired part and placing reinforcing fibers within structurally thin sections. The apparatus of the invention is a moveable ram that may be tapered and that is in contact with the charge during forming.

A template for imprint lithography can include a body. The body can include a base surface and a recession extending from the base surface. The recession can have steps and a feature. The steps can include a distal step that is farther from the base surface as compared to any other step, each step having a corresponding height. The feature can include the distal step includes a rounded or tapered sidewall; a surface along a deepest part of the recession is non-planar; or the height corresponding to the distal step is different from an average height corresponding to remaining steps. The template can be used in an imprint lithography apparatus. The template can be used in manufacturing articles when patterning different layers at the same time. The template is well suited for forming 3D memory arrays.

A curable composition contains a polymerizable compound, a photopolymerization initiator, and a solvent. The polymerizable compound contains a silicon compound having polymerizability, the curable composition has a viscosity of not less than 2 mPa.Math.s and not more than 60 mPa.Math.s at 23 C., the curable composition in a state in which the solvent is removed has a viscosity of not less than 30 mPa.Math.s and not more than 10,000 mPa.Math.s at 23 C., and content of the solvent with respect to the whole curable composition is not less than 5 vol % and not more than 95 vol %.

A pressing tool is provided for producing fiber composite components, including a first tool part and a second tool part moveable relative to the first tool part. In the closed state of the pressing tool, the two tool parts form a shaping cavity for accommodating a fiber semi-finished product to be shaped and each have a tool surface delimiting the cavity. In addition, at least one of the tool surfaces has at least two adjacent flat sections inclined toward each other which are connected to each other by way of a curved transition section. The curved transition section has at least one groove-shaped recess facing the cavity.

The present invention relates to a method of moulding a composite article using a mould. The mould includes first and second rigid mould parts between them defining a mould cavity. A reservoir of resin is connected to an inlet into the mould cavity. A suction pump is connected to a port on the opposite side of the mould cavity from the inlet. At least one of the mould parts has an arrangement of grooves on the surface facing the mould cavity to distribute resin across the mould cavity. The method includes laying up fibres in the mould cavity, injecting resin from the reservoir by running the suction pump to fill the mould cavity with resin, curing the resin article to form a moulded article and opening the mould and removing the article.
