A fiber-reinforced resin hollow body includes an axial-direction fiber layer containing reinforcing fibers aligned parallel to an axial direction of the hollow body, and a non-axial-direction fiber layer provided on top of at least one of an internal and an external side of the axial-direction fiber layer, and containing reinforcing fibers oriented in a direction different from a direction in which the reinforcing fibers contained in the axial-direction fiber layer are aligned. The non-axial-direction fiber layer has end portions in a peripheral direction of the hollow body, the end portions overlapping each other.

A fibre reinforced polymer (FRP) composite structure incorporates a woven preform containing tows of carbon or other advanced fibres and wires of shape memory alloy (SMA). The SMA wires are capable of absorbing much larger amounts of strain energy than the conventional components of FRP composites and hence enhance the impact resistance of the structure. The woven form incorporates the SMA into the structure in an optimum manner in terms of handling and performance.

According to one embodiment, a system for manufacturing a fully impregnated thermoplastic prepreg includes a mechanism for moving a fabric or mat and a drying mechanism that removes residual moisture from at least one surface of the fabric or mat. The system also includes a resin application mechanism that applies a reactive resin to the fabric or mat and a press mechanism that presses the coated fabric or mat to ensure that the resin fully saturates the fabric or mat. The system further includes a curing oven through which the coated fabric or mat is moved to polymerize the resin and thereby form a thermoplastic polymer so that upon exiting the oven, the fabric or mat is fully impregnated with the thermoplastic polymer. During at least a portion of the process, humidity in the vicinity of the coated fabric or mat is maintained at substantially zero.

A marking tape for application on pavement which comprises a core layer and an adhesive layer outside the core layer. The core layer is formed of a combination of a conforming layer of a thermoplastic material, a marking layer of a cross-linked material, and a fibrous layer. The conforming layer and the marking layer are contiguous and/or directly interconnected with each other. The marking tape is preferably relatively light weight and relatively inexpensive.
