A fiber structure for a fiber-reinforced composite material includes a section in which a width varies continuously along a central axis in a plan view. In a section in which the width increases continuously along the central axis, discontinuous fibers are aligned radially along the central axis, and both a thickness of the fiber structure and a density of the discontinuous fibers are uniform.

Disclosed is a cover for a utility vault and a method for making such covers. The cover is formed from fiberglass reinforcement layers, a low-density core, and a polymer mix matrix. The reinforcement layers include a bottom reinforcement layer, one or more edge reinforcement layers, and a top reinforcement layer. A first portion of the edge reinforcement layer overlaps a portion of the bottom reinforcement layer and a second portion of the edge reinforcement layer overlaps a portion of the top reinforcement layer. The core is positioned between the top and bottom reinforcement layers. The reinforcement layers are formed from fiberglass fabric and may include fiberglass layers whose fibers are oriented quadraxially. The polymer mix impregnates the fabric layers, encases the core, and binds the components together. The polymer matrix includes a thermoset polymer resin.

A method for manufacturing a transparent composite material including preparing a film coated with a transparent resin, unidirectionally aligning glass fiber filaments and manufacturing a glass fiber plate by embedding the unidirectionally aligned glass fiber filaments in the transparent resin, wherein the transparent resin includes SiOSi bond and one of methyl, ethyl and phenyl.

A staple cartridge for stapling the tissue of a patient is disclosed. The staple cartridge comprises a cartridge body, a plurality of staples, and a compressible tissue thickness compensator configured to adapt in thickness in response to the thickness of the tissue and adaptively apply different pressures to the tissue based on the thickness of the tissue captured within the staples. The compressible tissue thickness compensator comprises a plurality of fibers comprising a first matrix oriented in a first direction and a second matrix oriented in a second direction that is different than the first direction. A network of interstices is defined intermediate and among the first matrix and the second matrix. The network of interstices comprises a plurality of cavities that promote tissue and cellular ingrowth between the first and second matrices of fibers.
