A method and system for the characterization of equibiaxial compressive strength in 2D woven composites, such as carbon fiber reinforced laminate composites, is disclosed using induced biaxial flexure, the strain measurements from which are used to determine the equibiaxial compressive strength of the composite.

An object of the present invention is to obtain a fiber-reinforced composite material achieving both lightweight properties and mechanical properties at a high level. The present invention provides a fiber-reinforced composite material including a resin (A) and a reinforcing fiber (B), and having: a porous structure portion having micropores with an average pore diameter of 500 μm or less as measured by a mercury intrusion method; and a coarse cavity portion defined by the porous structure portion and having a maximum length of more than 500 μm as a cross-sectional opening portion.

The present invention relates to the field of air filtration, in particular to a polytetrafluoroethylene composite filter material. The polytetrafluoroethylene composite filter material comprises a supporting layer and a polytetrafluoroethylene film layer, wherein the supporting layer is a silver-plated carbon nanomaterial-modified meltblown nonwoven fabric. The polytetrafluoroethylene composite filter material is prepared by fiberizing a resin material modified by silver-plated carbon nanomaterial on the surface of a polytetrafluoroethylene film by a melt-blowing method. The polytetrafluoroethylene composite filter material of the present invention combines filtering and sterilizing functions, has higher filtering efficiency and filtering precision, has the functions of sterilizing and killing viruses, has a good isolation effect, and greatly prolongs the service life of the filter material.

The disclosure provides an interior trim part for a motor vehicle having a sliding or panoramic roof comprising a headliner and a stiffening frame attached to the headliner and enclosing and stabilizing an opening in the headliner enclosing the sliding or panoramic window, the stiffening frame being made of a fiber-reinforced composite material comprising a fiber mat and a textile lattice material, the textile lattice material being applied over a surface of the fiber mat and impregnated together therewith.

Provided is a heating device including: a heating unit that heats a laminate which includes a plurality of sheet-like composite materials including reinforced fiber and thermoplastic resin, and heats, via a first contact surface disposed in contact with the laminate, the thermoplastic resin included in the laminate being in contact with the first contact surface to a softening temperature or higher; a cooling unit that cools, via a second contact surface disposed in contact with the laminate, the thermoplastic resin included in the laminate located outside of the second contact surface to a temperature lower than the softening temperature; and a pressing unit that applies a predetermined pressure to the laminate via the first contact surface and the second contact surface, the second contact surface being disposed so as to surround the first contact surface.

An article includes a completed fabric structure that has multiple plies of fiber reinforced fabric. A first portion of the fabric structure has a three-directional fiber reinforced configuration and, exclusive of the first portion, a second portion of the fabric structure having a two-directional fiber reinforced configuration.
